When did Edmond Becquerel discovered the photovoltaic effect?
1839
Photovoltaics transforms incoming light into electrical energy. Its underlying principle, the photoelectric effect, was discovered in 1839 by Alexandre Edmond Becquerel (1820 – 1891).
Who talked about the idea of photoelectric effect Mcq?
The photoelectric effect was discovered in 1887 by the German physicist Heinrich Rudolf Hertz. In connection with work on radio waves, Hertz observed that, when ultraviolet light shines on two metal electrodes with a voltage applied across them, the light changes the voltage at which sparking takes place.
How did Edmond Becquerel discovered the photovoltaic effect?
Edmond was interested in light and studied the phenomena of fluorescence and phosphorescence. In 1839 he placed two electrodes in an acidic solution and exposed one of the electrodes to light. He found that the device generated electricity. Becquerel had created the first photovoltaic cell.
Who discovered photoelectric effect Einstein or Hertz?
Heinrich Rudolf Hertz
The photoelectric effect was discovered in 1887 by the German physicist Heinrich Rudolf Hertz. In connection with work on radio waves, Hertz observed that, when ultraviolet light shines on two metal electrodes with a voltage applied across them, the light changes the voltage at which sparking takes place.
Which German physicist discovered the photoelectric effect in 1887?
Heinrich Hertz
Heinrich Hertz, a German physicist, discovered the photoelectric effect in 1887. He observed that shining an ultraviolet light on electrodes caused a change in the voltage between them. Other work during the 19th century built on Hertz’s observations.

Solar cell/Inventors
In 1883, American inventor Charles Fritts made the first solar cells from selenium. Though Fritts had hoped his solar cells might compete with Edison’s coal-fired power plants, they were less than one percent efficient at converting sunlight to electricity and thus not very practical.
